GENERAL INFORMATION The Chameleon is an add-on module of the modular FREE/FREE+/BeFREE family which combines 16 LCD keys with 12 standard mechanical keys. It can be pictured as a keyboard that dynamically changes its appearance (key inscriptions and backlight colours) and function (key codes). This “chameleon like” self-changes follow either predefined page structures (Off-Line Operating Mode) or commands received from the host system (On-Line Operating Mode). Integrated LCD keys are push-button keyswitches with built-in graphic display. A liquid crystal display is integrated within the key. The resolution of the display is 32 x16 pixels. Each pixel can be turned on or off individually, allowing the display of two lines of text or detailed graphics. Furthermore, LED background lighting is integrated in the display, which makes the displayed graphics readable in dark operating environments. An additional advantage of the background lighting is the ability to notify the operator. Different operating conditions can be indicated by different colours. The alerting effect can be improved by alternating (blinking) backlight colours using several predefined rates. A.1.

GENERAL INFORMATION A-4 A.3. Operating Modes Chameleon can dynamically change its appearance and function. Those “transformations” can be controlled either from within the module (Off-Line Operating Mode) or from the host system (On-Line Operating Mode). The module incorporates non-volatile memory (Flash, 1 Mbit capacity, 10 000 write cycles minimum, 10 years data retention) for permanent storage of user-defined settings. The memory is divided into two major parts. The first one is a library of up to 256 icons (bitmaps) to be displayed on LCD keys and the other one is the application area describing the required operation. The application area is divided into up to 24 “pages”. Each page describes properties of all 16 LCD keys that are simultaneously active. The properties are: ♦ Graphics to be displayed on the LCD (i.e. pointer to one of 256 predefined icons within the library) ♦ Normal (black on white) or reversed (white on black) graphics ♦ Two backlight colours (Colour 1 and Colour 2) to be alternated by required blinking rate (also referred to as alternating frequency). Colour 1 and Colour 2 can be selected from the palette of 64 different colours, plus “no colour” when backlight is turned off. ♦ Backlight alternating frequency (2.0 Hz, 1.0 Hz, 0.5 Hz and 0 Hz) between Colour 1 and Colour 2. If the frequency is set to zero, it means steady backlighting in Colour 1. ♦ Sequence of codes to be sent towards the host system upon key press and/or key release. ♦ “Change Page” action upon key release: Page Up, Page Down, Home, End, Go To Page No, Stay In Actual (Don’t Change) All the properties can be independently defined for each of the 16 LCD keys within each of up to 24 pages. In total, up to 24 x16 = 384 different settings are allowed. This “page structure” is applicable exclusively for 16 LCD keys. 12 mechanical keys are treated separately and their properties are constant no matter which page is currently active. Properties of mechanical keys are: ♦ Sequence of codes to be sent towards the host system upon key press and/or key release. Up to 4 different sequences can be defined for each key (which differs from LCD keys with single sequence per key). ♦ “Change Page” action upon key release: Page Up, Page Down, Home, End, Go To Page No, Stay In Actual (Don’t Change) All above settings for LCD keys and mechanical keys are user definable by means of “ChangeMe” software utility operating under Windows operating systems. CHAMELEON – TECHNICAL OVERVIEW A. GENERAL INFORMATION A-5 A.3.1. Off-Line Operating Mode This is the default operating mode, also referred to as “Stand-Alone” operation. Once all the settings are defined and stored within the module’s non-volatile memory, the module is ready for Off-Line operation. After the power-on it loads the Home Page (Page 0) and waits for a keystroke. The module itself, by means of predefined “Change Page” actions, navigates through the pages (i.e. switching between different keyboard layouts). A.3.2. On-Line Operating Mode In On-Line mode (also referred to as “Real-Time” operation) the host system controls what is currently displayed on LCD keys. The module can execute the following set of commands received from the host: ♦ Go On Line The module will switch to On-Line operating mode (until reset or new power-on condition), load the Home Page properties and disable “Change Page” actions for both LCD keys and mechanical keys. ♦ Display Icon The module will display selected icon from the library on the addressed LCD key. ♦ Display Bitmap The module will display required bitmap (passed as the command arguments to the module) on addressed LCD key. ♦ Change Backlighting The module will set required backlighting (Colour 1, Colour 2 and blinking rate) for the addressed LCD key. ♦ Go To Page The module will load the selected page (n). Page number (n) should be within the range from 0 up to (N-1), where the N is total number of preprogrammed pages. ♦ Get Page Number The module will return the actual page number (n) and total number of pages (N). ♦ Go On Line Permanently The module will remain in On-Line mode even if the power is removed, so the OnLine becomes default operating mode. ♦ Return Off Line Permanently The module will recover factory-preset default operating mode. A.4. Power Consumption Current consumption of the Chameleon, depending on selected backlighting colours, may exceed 500 mA, what is the limit of USB computer ports. Therefore, an additional CHAMELEON – TECHNICAL OVERVIEW A. GENERAL INFORMATION A-6 +5V power supply (e.g. TM-VPA) is compulsory, except in cases when the Chameleon module is used within a configuration comprising a Powered FREE+ touchmonitor or a BeFREE touchcomputer.
